Thomas Bandholtz blogs about cool-URIs in a RESTful World.

He summarized literature about URIs, SOA, and REST into something combined:
RESTful SOA may argue that this mainly fits for a provision of fix document files. A dynamic SOA server can easily implement this “generic” URI concept without any redirection, just by rendering the content in the requested format on demand. This view satisfies content provision, while the redirection architecture better supports linkage and reference. It also leverages resource management and governance, be it in the Semantic Web, or in RESTful SOA. And may be these two application areas are not so distinct from each other.
